The flower food for bigger blooms

WonderFert Flower is a liquid fertilizer formulated to support greater blooming and flowering in your garden.

Specially formulated with higher phosphorus levels, it focuses resources directly on flower and fruit productivity. Its liquid formula absorbs quickly to kick-start growth, while its slow-release ingredients sustain growth. Need more flower power? The potassium and seaweed extract combination increases stress tolerance, so your plant can grow more vibrant blooms.

At Sunday, we believe in creating fertilizers without pesticides or harsh chemicals—so you can enjoy your yard and get your hands dirty—not your plants.

Product Features:

  • Specialized 3-8-7 NPK (Nitrogen-Phosphorus-Potassium) flower food
  • Water and fertilize in just one step
  • Made for roses, flowers, and flowering plants
  • Encourages bigger flowers, greater yield and improves stress tolerance
  • Safe for use on edible plants
  • Non-staining formula
  • Covers up to 500 sq. ft.
  • Includes concentrated plant food formula in 100% post-consumer recycled container and gentle garden hose-end sprayer

Ingredients:

Nitrogen: Slow-release fertilizer for sustained feeding

Phosphorus: For flowering and fruiting

Potassium and seaweed extract: For plant health and stress tolerance


Instructions:

  1. Best used in early spring until early summer, before peak heat. Apply during the early morning or late evening, and make sure the area is well-hydrated before application.
  2. Attach the hose-end sprayer to the bottle. Set the sprayer to the recommended setting for trees and shrubs.
  3. Spray evenly at the base of each tree and shrub. Avoid over-spraying—a few seconds per plant is sufficient.
  4. Water the treated area lightly to help the fertilizer penetrate the root zone.
  5. Reapply every 4-6 weeks during the active growing season to maintain optimal nourishment.

Helpful Tips from Lawn Advisors:

How does liquid flower food enhance bloom quality and quantity?

With its high PK content and seaweed extract, it promotes vigorous root and flower development.

Its unique seaweed extract formula and high PK content cater specifically to flowering plants.

What’s the difference between WonderFert Flower and other liquid flower garden fertilizers?

When it comes to flower food, there are many options to choose from. We formulated ours to provide higher levels of phosphorus and potassium to boost blooms and added seaweed for greater resilience to growing season stressors. Beyond a seaweed-powered formulation, WonderFert Flower offers dual application via hose and watering can, covers more square footage (up to 500 sq. ft.), and offers less frequent applications (every 4-6 weeks).

How does seaweed extract support flowers?

Seaweed extract aids flowers by reducing stress and enhancing yield. Plus, its natural nutrients support healthy development and resilience in flowering plants.

Is WonderFert Flower suitable for all types of flowering plants?

It's ideal for various flowering plants, including roses, annuals and perennials, container plants, and fruiting plants. It may not be suitable for flowering plants that aren’t well-suited for or do not require fertilization.

How to use with other Sunday products?

If using other Sunday products, let liquid fertilizers dry completely before applying anything else to your garden. For best results, use our liquid garden fertilizer in combination with Sunday’s dry organic fertilizer, Soil Boost, and weed control. This will help you fertilize plants properly, reduce weeds, and introduce nutrients back to your soil.
